VALVE.

Specification of Letters Patent.

.Application tiled December 5, 1911. Serial No. 664,016'.

To all 'whom z't may concern:

Be it known that I, ARTHUR B. UTLEY, a citizen of the United States, anda resident of Springfield, in the county of Greene, Sta-te of Missouri,have invented a new and useful Improvement in Valves, of which thefollowing is a specilication.

My invention is an improvement in valves, and has for its object theprovision of a simple valve for use with flushing tanks for controllingthe flow of water to the tank, wherein means is provided for quicklyclosing the valve at the proper time, regardless of the water pressure.

lagainst the rib 2b of the 11 has its ends 12 and 13 reduced, and the Inthe drawings: Figure 1 is a transverse vertical Section of a tankprovided with the improvement; and Fig. 2 -is anenlarged side view withparts in section.

In the present embodiment of the invention the tank 1 is of usualconstruction, and the pipe 2 passes in`to the tank through the bottom 3thereof, and the joint between pipe and tank is packed water-tight by awasher 4 encircling the pipe on the upper face of the bottom, and a nut5 encircling the pipe below the said bottom.

The pipe 2 extends upwardly in the tank to the required water level, andone end of an elbow 6 is threaded onto the pipe.

A pipe 2a is threaded` into theother end of the elbow, and the said pipeis provided at its outer end with an annular rib 2". A reducing sleeve7-8 is abutted against the end of the pipe 2a, the said sleeve having an'annular shoulder or rib 9 abutting plpe 2a.

end 12 tits over the large end 7 of the sleeve, and against theshoulder, 9, and a union nut is threaded on to the end 12. The saidunion nut is provided with an internal annular shoulder 10a at the endadjacent t0 .the elbow for engaging the rib 2b. When the union nut isthreaded on to the end 12,

the end of the pipe 2a will be compressed against the end of thereducing sleeve.

Thereducing sleeve is the valve seat, and the small end 8 thereofextends into the body of a T or casing 1l to ap roximately the lon, 3',itudinal center thereo.) A valve 14, in the form of a plug, is s'lidablein the -end 13 of the T, and the inner end of the plug is recessed at 15to receive the end of the saidsmall end to close the same.

The stem 16 of the valve extends outside of the T and is provided with-avertical A casingy opening 17. A l'ever 18.has one to a bracket arm 19on the a screw 20, and the lever passes through thc opening, ijtting thesaine loosely, as shown.

The lower end of the lever 18 is widened and is slotted longitudinally,as shown at 21, and the slot is enga ed by a roller 22 on one arm 23 ofan e bow lever 23-24, whose other arm 24 has connected therewith a ballfloat- 25. The elbow lever is )ivoted to a bracket arm 2G extendinglaterally from a pipe 27, which is threaded into the lateral nipple 28of the T.

'lhe arms 23 and 24 of the elbow lever end pivoted T by means of arearranged at an acute angle with respect to each other, and a bolt 29pivot-ally connects the elbow lever to the bracket arm, passing throughthe arm 23 of the elbow lever near its junction with the other arm. Thefloat is secured to the free end of arm 24 of the elbow lever by meansof a bolt 30 passed through a bearing 3l on the arm, and through thefloat, the bolt being engaged by a nut 32 to hold the parts in place.

That portion of lever 18 between the slot and the screw 20 isarc-shaped, and the slot 21 is also arc-shaped. The pipe 27 extends tonear thebottom of the tank, the lower end being spaced above the bottomsuilciently to not interfere with the flow of the water.

In operation, when the tank is opened to flush the closet the float 2moves downward asthe water leaves the tank into the dotted line positionof Fig. 2. As the arm 24 is swung outward and downward, the/ lower endof lever 18 is swung outward until it engages the outer end of slot 17.A considerable movement of the float takes place before valve 14 isaffected. A'S soon, however, as lever 18 is moved to engage 'the outerend of slot 17 the valve bevins to open, to permit the water to flowii'om pipe 2 through 'the T and pipe 27 into the tank. As the tankfills, the movement of the float is reversed, until the water reachesthe required level, when the valve is completely closed to shut off thewater. It will be noticed from an inspection of Fig. 2 that when thefloat is moving from the dotted line to the full' line 'position thepressure against lever 18 is directly inward, the roller rolling downthe inner side of the slot 21. The leverage is very great, and the valvecloses very readily on'ths e count, although the pressure to beovercome, that from the main, is

also great. The inner end of the'valve 14 may be of compressibleandelastic material,

as, for instance, leather or rubber, to make a .close fit.

The nut 10 is provided with an external annular polygonal rib 33 forengagement bly a wrench, and may be turned toward the e bow to releasethe sleeve 7-8 and the end 12 of the T, when it is, for any reason,desirable to obtain access to theparts.

I claim:

1. In combination'wth the tank and the supply .pipe leading upwardlythrough the bottom thereof and opening laterally at its top and havingan annular external rib at its outer end, a reducing sleeve havin'or itslarge end abutting against the end of the ipe, said sleeve having anexternal annuar rib at the said end, a T having its ends reduced, one ofthe opposite ends fitting over thek large end of the .reducingsleeve-and abutting against the rib, and a union nut having an internal.annular rib engaging the rib of the pi e/and threaded at its oppositeend on to t e adjacent end of the T, the

small end of the reducing sleeve extending into the body of the T,a"valve plug slidable in the other VVreduceob' end of the T and adaptedto engage the small end of the reducing sleeve to close the same, thelateral opening ofthe beingI downward, a discharge pipeconnected-therewith and opening near the `bottom of the tank, means foroperating the valve, said means comprlsng a lever pivoted' at its upperend, vthe plug having a vertical opening for receiving the leverloosely, said lever havinga longitud-v4 slot, and a float connected withthe other arm.

2. In combination with the tank and the supply pipe leading upwardlythrough the bottom thereof and opening laterally at its top, a reducingsleeve having its large end engaging the lateral opening, a walvemovable toward and from the small end of the reducingsleeve, said valvehaving a vertical opening, a lever pivoted at its upper end andextending through the opening,

said lever having a slot at its lower end, an elbow lever pivoted belowthefirst named v lever, a roller on one arm of the elbow lever engagingthe slot, and a vioat on the other arm.
